Evaluating the effectiveness of training for operators of organic fertilizer equipment can be done by:

1. Written examination: The written examination is passed to test the operator's mastery of the operating procedures, safety knowledge and equipment maintenance of the organic fertilizer production line.

2. Theoretical knowledge question and answer: oral or written question and answer to check the operator's understanding and memory of the training content.

3. Simulation operation: Let the operator operate the equipment in a simulated environment, and observe whether it can start, run, stop and other operations in accordance with the operating procedures.

4. On-site operation demonstration: Let the operator perform the operation demonstration on the actual equipment to evaluate the accuracy and standardization of its operation.

5. Safety knowledge test: Test to assess the operator's understanding of safe operating procedures and emergency handling measures.

6. Emergency drill performance: Observe the operator's reaction speed and processing ability in emergency drill, and evaluate its performance in emergency situations.

7. Production efficiency: Evaluate the effectiveness of training by comparing the production efficiency of operators before and after training.

8. Equipment failure rate: statistics of the failure rate of the equipment during the operation of the operator, and the reduction of the failure rate indicates that the training effect is good.

9. Operator feedback: Collect operator feedback on training content, methods and effects, and understand the problems and difficulties encountered in actual work.

Through the comprehensive application of the above methods, the training effect of organic fertilizer equipment operators can be comprehensively evaluated to ensure that they have the ability to operate equipment safely and efficiently.
